Dear Bo,
Are the ^M control characters really at the end of each line in your input
file? If so then you have a DOS formatted text file which has a Carriage
return and a line feed at the end of each line of text instead of just a
line feed. This is most likely confusing Sander. Try converting it to a unix
format text file:
dos2unix myfile.in (Assuming dos2unix exists on your machine)
Also, you may have a problem if the &cntrl flag is in the wrong place. The &
character has to be in the SECOND column of the file. E.g your file should
look like this (Assuming email formatting doesn't muck this up):
TITLE FOR JOB
&cntrl
imin=1,
maxcyc=200,
ntpr=5,
/
(You can use &end instead of the / but some machines don't like this. The /
should work on everything)
If you still get a problem try attaching the input file to your email.
All the best
Ross
